What is the purpose of the continue statement in Python?

The continue statement is a control flow mechanism used inside for or while loops. When the Python interpreter encounters a continue statement, it immediately stops the execution of the current iteration and skips the remaining statements in the loop's body. Control is then passed back to the top of the loop to begin the next iteration. For a for loop, it proceeds with the next item in the sequence. For a while loop, it re-evaluates the loop's conditional expression.

B. This describes the fundamental purpose of a loop structure (like for or while), not the continue statement which alters the flow within a loop.

C. This describes the behavior of an else block, which executes when the condition of an if statement or a loop is not met.

D. Defining functions is done using the def keyword, and exception handling is managed with try...except blocks; continue is unrelated to these operations.
